How to Fix Crackling or Popping Noises in BIAS X Audio Output

Symptom: You're hearing crackling, popping, or other artifacts in your audio output while using BIAS X.

How to Fix Crackling or Popping in Audio

1. Check System Requirements

   • Ensure your computer meets the minimum system requirements.

2. Increase Buffer Size and Adjust Sample Rate

   • Set your audio buffer size to 256 or 512 samples to reduce CPU load (latency may increase slightly).
   • Use a sample rate of 44.1 kHz or 48 kHz for better system compatibility.

3. Check Input/Output Settings

   • In the bottom bar of BIAS X, monitor input/output levels and avoid clipping.
   • Ensure your Input Mode (Mono or Stereo) matches your setup.
   • When using Stereo, select two active input channels—otherwise, BIAS X defaults to Mono.

4. Monitor DSP Load

   • Heavy presets can overload your CPU—try simplifying your signal chain.
   • Power off any unused gear modules.
   • Switch from Dual Amp to Single Amp mode for lower DSP usage.

   

   Don't see the DSP Load meter? Go to Settings > Preferences and enable it manually.

5. Close Other Apps and Background Processes

   • Quit any unnecessary background applications.
   • Use Task Manager (Windows) or Activity Monitor (macOS) to monitor CPU and RAM usage.
